Patented Oct. 23, 1945 Charles: D.- Bonsall, Chicago, IlL, assignor; by mesne assignments, to Standard Railway Equipment Manufacturing Company; a: corporation of Delaware Application August 25, 1943; Serial No. 500;182

4 claims.

The invention relates to railway freight cars of the house or roofed type and has for its object to provide means-for protecting the. wooden floors now in general use in such type ofjequipment, which means will not interfere with, the securing of blocking to the wooden flooring.

Another object is to protect the wooden flooring with a metallic sheathing which is. perforated so that the car lad'ing may be, secured to the flooring through the apertures.

The fioorsof railway cars are subjected to a great deal of abuse by nails and spikes being driven into them when attaching blocking to them, and also by trucking the lading into the car and by dragging pieces of lading from one part of the car to another. That portion of the car between the opposite side wall doorways is given the most abuse by lading being hauled through the car (by truck or otherwise) to an adjacent car. However, my improved floor protection may be applied over the entire area Of the floor if desired.

Another object is to provide the floor sheathing with an extension to cover and protect the part of the wooden flooring between the side door posts of the railway car, which part forms the threshold of the doorway. The threshold is subjected to a great deal of abuse and wear by the above mentioned trucking.

The lower portions of the door posts are subjected to considerable damage by the wheels and sides of the freight handling trucks hitting the posts as they are rolled in or out of the car, therefore, another object of the invention is to also provide the floor sheathing or floor protecting sheet with means to protect the lower portions of the door posts.

Another object is to provide a floor protection which may be easily installed and parts of which may be easily removed and replaced when it is desired to repair the floor.

Other objects and advantages of my invention will be apparent from the following detailed description by referring to the accompanying drawings.

In the drawings:

Fig. 1 is a cross section through the lower part and doorways of a railway car provided with my improved floor protecting sheet.

Fig. 2 is a section through the door posts and doorway looking down on the floor protecting sheet.

Fig. 3 is a section through the doorway at the side sill showing the floor protecting sheet and associated parts.

Fig. 4. shows a separate door. post protecting plate.

Fig- 5 is a. perspective view of the improved floor protecting, sheet, per se.

Fig. 1 shows the woodenfloor. 2';v door posts 3'; doorway threshold, 4;, center sills 5}. side sills. E; floor protecting. sheet-land the attachihgbolts 8.

The protecting sheet T is provided with a.plurality of apertures ill so that the car lading may be secured to the wooden flooring 2 through said apertures.

The floor protecting sheet! preferably extends between the doorways on opposite sides of'the car and protects both thresholds 44.

The protecting sheet 1 extends between the door posts 3 on opposite sides of the doorway so as to protect the part of the wooden flooring forming the threshold of the doorway and is preferably formed with a downturned stiffening flange l2 which also protects the edges of the wooden floor boards 2 from abrasion and the weather.

The portion of the protecting sheet between the door posts is provided with an upstandin flange [4 adjacent each door post to protect the lower part thereof. These flanges are adjacent and secured to the sides of the door posts 3 facing the doorway preferably by welded material, or if desirable, the bolts IS.

The protecting sheet I is also provided with an upstanding flange I 6 adjacent and secured to the sides of the door posts 3 facing the interior of the car. These flanges l6 are preferably integral with the flanges l4 secured to the sides of the posts facing the doorway. Preferably these flanges l4 and I6 are welded together and to the door posts 3 after in place on the car.

Fig. 4 shows a door post protecting plate l8 covering the lower portion of each door post which is preferably welded to the posts 3 and protecting sheet I. This plate I8 comprises flanges l9 and 20 corresponding to M and I6, respective ly, and also a flange 2l for attachment to the floor protecting sheet I.

The upstanding flanges M or the protectin sheet 1 may be extended to engage and be secured to the front (23) and rear (24) door weather strips by welded material. These weather strips are secured to their respective door posts.

The accompanying drawings illustrate the preferred form of the invention, though it is to be understood that the invention is not limited to the exact details of construction shown and described, as it is obvious that various modifications thereof, within the scope of the claims, will occurto persons skilled in the art.

apertures, said protecting sheet extending between said door posts and weather strips to protect said threshold and extending beyond saiddoor posts and being downwardly turned to provide a protecting flange for the outer edge of the threshold, said protecting sheet provided with upstanding flanges secured to the sides of the door posts facing the doorway and to said weather strips,

and other upstanding flanges secured to the sides of the door posts facing the interior of the car.
